Description of KOOKYE Nano V3.0 ATMEGA328P Module CH340C 5V 16M Mini USB Micro-Controller Board for Arduino (Nano5) - Enhanced Performance and Connectivity

The Nano for arduino is a compact board similar to the UNO.The Nano for arduino is a small, complete, and breadboard-friendly board based on the ATmega328P (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. The Nano for arduino can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source. Each of the 14 digital pins on the Nano can be used as an input or output.They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions. The Nano has 8 analog inputs,each of which provide 10 bits of resolution.By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. Analog pins 6 and 7 cannot be used as digital pins. Additionally, some pins have specialized functionality. The Nano for arduino has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers.Such as UART TTL (5V) serial communication and I2C (TWI) and SPI communication。.

Strange initial firmware procedure, but generally it works.

They seem to work well enough, so far I've only configured one with TMK keyboard firmware to enable the PS/2 to USB adapter. It's interesting to note that while grounding and resetting the pins works fine for the second one, once I've flashed some firmware on it, it doesn't seem to work with the original firmware. Maybe it has something to do with avrdude, but I had to hold the reset and contacts together for a good two or three seconds to actually get anything to blink. For those interested, I

Pros
  • Expensive but decent
Cons
  • Repair

Operation when the USB bus is switched off. Do not operate with a 12V power supply

As others have found out, the voltage regulator used in these "clones" Pro Micro does not handle 12V. Once the regulator is blown I would assume it's the 6V to 5V LDO regulators on the output. I can't say for sure without the data sheet. I say this because most regulators have a "maximum operating voltage" which is the normal operating range, and then they have an "ABSOLUTE maximum voltage" which is higher than the maximum operating voltage. Voltage at which the device can withstand Abs. Load…

Plug and play, price list

SparkFun Pro Micro clone. Get 3 for 1 SparkFun board. Note: PROGRAM LIKE LEONARDO. I looked at the reviews and some users had trouble uploading the sketches. I chose the Arduino Leonardo as the board and was able to upload without any problems. There are 3 LEDs, one for power and one each for RX and TX. VCC output 4.5V when powered by USB. Silkscreen is also stuffed fairly densely, but legible. Three boards came in a box, each in its own anti-static bag with 3 rows of pins. Bonus points for the

Great little prototyping board

I had trouble with this initially. To be honest, I didn't know there was such a thing as a micro USB cable with no data cables attached. It was supplying power, so the LEDs were lit, but there was no communication. I almost went insane troubleshooting until I tried a different cable. As if that wasn't enough, I fell into another trap right after. Set the Arduino IDE to "Leonardo" as suggested by the manufacturer. I figured if this is a Sparkfun Pro Micro clone it should be programmed as one…

Pros
  • Best in the niche
Cons
  • No paint required

It may take a few tries to get used to re-flashing, but it works well.

Already bought twice. I've read that several people mention the risk of getting a non-working board for other products. Find it great and no problems. There was a command in the customer comments for their firmware that I ran several times on my Mac, something like this: avrdude -c avr109 -p atmega32u4 -P /dev/cu.usbmodem1 -U flash:w:filename. hexGround pin 3 and when it starts blinking you should see /dev. It should be noted that sometimes it didn't release the device, so when resetting it…

Pros
  • The best
Cons
  • A few little things
